Description

Technical Field

[0001] The invention relates to the technical field of caulking agent production devices, in particular to a stirring preparation device for caulking agent for door and window frames and a caulking agent preparation method based on the device. Background Art

[0002] As an important building material, caulking agent is widely used to fill gaps in door and window frames to ensure the integrity and aesthetics of the structure. Its raw materials are usually composed of solid particles, liquid and paste. Caulking agent is generally made of two groups of raw materials, AB, and the two groups of components have a certain proportion and composition. During its processing, the two groups of components are mainly processed separately under high pressure using different reactors, which affects the processing efficiency and quality. Some of them use ordinary stirring and dispersing devices for auxiliary processing to improve the processing reaction efficiency, but it is still difficult to effectively disperse solid particles, especially when the viscosity of the mixture is high, it is more likely to cause particle agglomeration, affecting the uniformity and stability of the material. At the same time, the stirring process of the caulking agent is also greatly affected by temperature. Excessive temperature will cause the viscosity of the mixture to decrease, and even dehydration or condensation will occur, resulting in lumps, affecting the stirring uniformity of the material. This uneven dispersion not only affects the final performance of the caulking agent, such as strength and adhesion, but also causes the caulking agent to crack after use. Traditional reactors or stirring devices often cannot effectively solve this problem, especially when the viscosity of the mixed materials varies greatly. Even with a higher stirring speed and stronger stirring force, it is still difficult to achieve the ideal stirring effect, which in turn affects the quality of the finished filler.

[0003] The existing caulking materials used for the gaps in door and window frames generally have low strength, generally between 5-10MPa, and weak anti-seepage strength, only 0.2-0.4MPa, which makes it difficult to resist external water vapor erosion and pressure shock. In addition, the adhesion to the wall and aluminum is generally between 0.3-0.5MPa and 0.1MPa, which is prone to debonding and cracking. At the same time, the thermal insulation performance is also very poor, and it is impossible to effectively isolate heat transfer. In addition to the proportion of raw material components, after a variety of processing experiments, its mixing process is one of the keys.

[0004] Therefore, it is necessary to provide a door and window frame caulking agent stirring preparation device for door and window frame gaps, which can effectively improve the stirring uniformity of the caulking agent, prevent the raw materials from condensing into lumps, and has high strength and is not easy to crack, and a caulking agent preparation method based on the device.

[0033] (1) The present invention realizes a stirring preparation device for door and window frame caulking agent. The processing of the raw materials of the AB component mixture is completed by one device, replacing the processing of the reaction kettle. The caulking agent production device adopts two stirring and dispersing devices. The two stirring and dispersing devices are composed of a stirring barrel, an inner stirring rod and an outer stirring rod. The inner stirring rod is located at the center of the stirring barrel, and the outer stirring rod is close to the inner wall. The inner stirring rod and the outer stirring rod are synchronously rotated in the opposite direction, which effectively solves the problem that the traditional stirring device is difficult to disperse mixtures of different viscosities. Through the multi-layer staggered reverse stirring between the inner stirring rod and the outer stirring rod, the uniformity of the A and B raw materials during stirring and dispersing is improved, thereby improving the toughness and adhesion of the caulking agent in the final product, preventing cracking, and realizing the synchronous processing and mixing of the A and B raw materials;

[0034] The two sides and the bottom of the outer stirring rod are equipped with scrapers, which are in contact with the inner wall of the stirring barrel, and can effectively remove the raw materials on the inner wall and the bottom of the stirring barrel to prevent the raw materials from condensing into lumps. At the same time, the stirring process is more thorough and uniform, thereby improving the stirring effect. In addition, a heating plate is provided at the bottom of the stirring barrel to heat the inside of the stirring barrel, and cooperate with the insulation layer to improve the insulation effect, reduce the working time and power of the heating plate, reduce energy consumption, and reduce the impact of ambient temperature on the stirring effect of A and B raw materials, so that A and B raw materials can always remain in a liquid or paste state during stirring, and prevent the problem of excessive difference in the raw material component density ratio between the agglomerated area and the non-agglomerated area due to the agglomeration of some materials in the raw materials during stirring, which effectively improves the density uniformity of the finished caulking agent and the anti-seepage performance after use;

[0035] The side of the device is equipped with a discharge pipe, which is connected to the hydraulic filling machine and the mixer. The controller controls the working time of the hydraulic filling machine to accurately and automatically inject the A and B materials in the mixing barrel into the mixer. In addition, the multi-level staggered counter-rotation of the stirring rods 1 and 2 significantly improves the efficiency and uniformity of the stirring and dispersion, and avoids contact between the stirring rods.

[0036] (2) The preparation method based on the device is highly efficient and high quality. The caulking agent has excellent bonding and impermeability properties, and can firmly bond the wall to the aluminum material. It is not easy to crack even under high temperature and strong wind conditions. It is light in weight and easy to operate. The dry density is only 0.97, the wet density is about 1.30, and the strength exceeds 15MPa, which can withstand a certain pressure. The bonding force between the caulking agent and the wall and the aluminum material reaches 1.5MPa and 0.6MPa respectively, which can effectively fix the door and window frames. At the same time, the impermeability pressure can reach 1MPa to prevent moisture penetration. In addition, the caulking agent also has good thermal insulation performance, and the thermal insulation coefficient can reach 0.1W / mk. It does not sag during construction and has excellent overall performance. It is suitable for sealing and fixing door and window frames. BRIEF DESCRIPTION OF THE DRAWINGS

Part of water and butyl acrylate, acrylic acid, styrene, hydroxyethyl methacrylate, triisopropyl acrylate silicone grease, acrylic reactive emulsifier, and part of initiator are added to the stirring barrel 11 for pre-emulsification; a part of water, one-tenth of the pre-emulsified liquid and the remaining initiator are added to the stirring barrel 11, the temperature is raised to 88 degrees and kept warm for 30 minutes, the remaining pre-emulsified liquid is added dropwise, and the dripping is completed within 3.5 hours, the temperature is 84-88 degrees, and the temperature is kept warm for half an hour, and the temperature is lowered to 75 degrees, and an oxidant and a reducing agent are added to complete the reaction of the remaining monomers, and the temperature is kept at 75 degrees for half an hour, and then the temperature is lowered to 48 degrees and organic silane is added dropwise, and the dripping is completed in half an hour, and the temperature is maintained at 48-50 degrees, and the temperature is kept warm for half an hour, and then a neutralizer, a defoamer and a thickener are added;

[0064] A portion of water is stirred in the stirring and dispersing device 1, and then the driving motor 211 is started at a speed of 400-800 rpm, and a wetting agent, a preservative and a defoaming agent are added respectively. After stirring for 30 minutes, a thickener diluted with the remaining water is added for thickening;

[0065] During the stirring of the A and B groups, the scrapers 28 provided on both sides and the bottom of the outer stirring rod 102 contact the inner wall of the stirring barrel 11, scrape and remove the raw materials on the inner wall and the bottom of the stirring barrel to prevent the raw materials from condensing into blocks, and start the heating plate 3 through the controller, and cooperate with the insulation layer to heat the inside of the stirring barrel 11, so that the A and B raw materials can always remain in a liquid or paste state during stirring;

[0066] Weigh a certain amount of components A and B respectively into a mixer 7, with a ratio of A:B = 2.5:1, and stir for 5 minutes to form a caulking agent;

[0067] Weigh a certain mass of components A and B respectively into a mixer 7 in a ratio of A:B=2.5:1, and stir for 5 minutes to form a caulking agent. Then use an extrusion gun to extract a certain amount of the stirred caulking agent to fill the gaps on the foundation groove, keel, wall, roof and ground of the building, and dry them. Use a spatula to close the gaps.

[0068] The two stirring and dispersing devices 1 can control stirring and heating respectively. During processing, according to the different mixing processing time of groups A and B, the controller can automatically adjust the final synchronization time to perform the final stirring and mixing of A and B.

[0069] The processed door and window frame filler is used for construction. After testing, it can be used in autumn weather with strong winds of 5m / s and low humidity (below 30%), and in summer when the aluminum temperature is 55°C without cracking. It has a dry density of 0.97 and a wet density of about 1.30. It is a lightweight material with a strength of more than 15MPa, can bear weight pressure, and has a bonding strength of 1.8MPa to the wall and 0.8MPa to aluminum. It has an anti-seepage pressure of 1.2MPa and a thermal insulation coefficient of 0.1W / mk. It has good construction performance and does not sag.

[0070] It has significant effect compared with conventional caulking materials sold on the market, which usually take 3-5 days to dry, have a strength of only 5-10MPa, a water-resistance of 0.2-0.4MPa, a bonding strength of 0.3-0.5MPa to the wall, and 0.1MPa to aluminum or steel, are prone to debonding and cracking, have weak water-resistance, and have almost no thermal insulation.

[0071] The caulking agent production device of the present invention solves the dispersion problem of mixtures of different viscosities by synchronously rotating two stirring and dispersing devices 1 and inner and outer stirring rods 102. The outer stirring rod 102 is equipped with a scraper 28 to effectively remove the raw materials on the inner wall of the stirring barrel 11 and improve the stirring uniformity. The bottom heating plate 3 is combined with the insulation layer to reduce energy consumption. The discharge pipe 5 is connected to the hydraulic filling machine 6 to ensure accurate and automatic injection.

[0072] The caulking agent of the present invention exhibits excellent adhesion and anti-seepage properties when used for door and window frames, ensuring good fixation with the door and window frames and effectively preventing moisture penetration. At the same time, the caulking agent is light in texture and high in strength, and can provide excellent thermal insulation effect, so that the thermal insulation coefficient reaches 0.1W / mk. In addition, during the construction process, the caulking agent is not prone to sagging, which facilitates the workers' operation and improves the construction quality.

[0073] Compared with the traditional reaction kettle processing time, the efficiency of processing the gap filler by using the above device is increased by 30%, and it is also very suitable for mass production.
